I'll lock tight all metal to metal connections, axles motor mounts etc. As far as cold weather running goes warm up the head with a hair dryer before starting. I would reccomend a old sock or foil wrapped around the the head, sett your idle trim up higher, and if possible run it several laps to warm it up. If you have a temp guage check the temp. You should have good smoke flying when you get on it. If its running real rough you may need to lean up the high speed needle, remember always tune the high speed first at it will effect the low speed screws fuel mixture as the fuel comes through thier first. Once the truck seems tuned and has good pick up to top end, and still smoking as you are getting on it, let it sit and idle try setting the throttle trim back to normal first if it falls off and stalls, lean the low speed fuel mixture slightly. When you pinch the fuel line the idle should pick up and then drop off it should be just about right your not trying to win a idling contest, and these 2 strokes will load up after idling longer then 30 seconds.

Im assuming your motor is broken in, if not just proceed more slowly during your break in with the above procedure and, the goal is to get it up to about 210 degrees during break in and shut your motor down, put the piston bdc and let it cool, and repeat the procedure for a couple of tanks, gradually leaning your motor up.

Now if your motor is to lean when you try to acelerate it will run a few feet, drop off and die. inspect the glow plug, if it is burnt brown, and the metal coil is all distorted try richening up.

I reccomend looking up break in procedures, but would follow the manufactures if your new to this. Cold weather break in is extra tough.

well if you have a servo that never returns to center with no input then yes. I have had mine last for weeks, running on the weekends. Make sure you are useing a name brand batt. I use the copper top and they hold up well.
